This seminal book on program evolution is currently out of print. With permission of the author and the publisher, we are pleased to offer you a scanned-in version of the book. It is a must-read, if only because it is one of the first books treating software evolution as a problem in its own right.
Indididual book chapters of the aforementioned Software Evolution book can be consulted here
